My panther chameleon is shaky and is not eating very well or at all. He is still drinking plenty and does not appear to be suffering from dehydration. I am trying to subsitute some reptile food that I got from the vet for another chameleon that would not eat after shipping and he seems to have no problem drinking that in. I am confused as what I should do. Also I have been mixing a little calcium w/ D3 in with the reptile food in case thats what it is. Any suggestions?
